I know this is long winded but I desperately ask...
NOW WHAT!!!
Live your life as if the relationship is over. She's obviously very confused, and frankly, it doesn't sound as if she knows what she wants. If the relationship with OM is truly over, and if there was never anything physical to begin with, then why is she ditching you for him? It sounds as if it's only when things didn't work out that she opened up to you and even that didn't sound very sincere.
I realize that all we have is your take on what happened, but if what you write is accurate, then she has much work to do on herself before she would be ready for a healthy relationship with anyone. You already said that you know she lies to you, so why would you even consider any of this healthy, and why would you want to put yourself in this position? Do you somehow think that you don't deserve anything better? Cause I gotta tell you, better is out there.
